I am somewhat convinced chain vaping lung hits will alter normal human breathing patterns

You and several others needs to stop acting like you drip 18mg. It's very dangerous to the lung tissue to drip that high especially sub ohm. I permanently damaged my lungs because of others on this forum telling me 18mg was regular. Sssstop it.

Speculation isn't fact. Back up your claims please.
